@GwtCompatible(serializable=true) public final class UnsignedLong extends Number implements Comparable<UnsignedLong>, Serializable
A wrapper class for unsigned long
values, supporting arithmetic operations.
In some cases, when speed is more important than code readability, it may be faster simply to treat primitive long
values as unsigned, using the methods from UnsignedLongs
.
See the Guava User Guide article on unsigned primitive utilities.

public static final UnsignedLong MAX_VALUE
public static UnsignedLong fromLongBits(long bits)
Returns an UnsignedLong
corresponding to a given bit representation. The argument is interpreted as an unsigned 64-bit value. Specifically, the sign bit of bits
is interpreted as a normal bit, and all other bits are treated as usual.
If the argument is nonnegative, the returned result will be equal to bits
, otherwise, the result will be equal to 2^64 + bits
.
To represent decimal constants less than 2^63
, consider valueOf(long)
instead.
public static UnsignedLong valueOf(long value)
Returns an UnsignedLong
representing the same value as the specified long
.
IllegalArgumentException
- if value
is negativepublic static UnsignedLong valueOf(BigInteger value)
Returns a UnsignedLong
representing the same value as the specified BigInteger
. This is the inverse operation of bigIntegerValue()
.
IllegalArgumentException
- if value
is negative or value >= 2^64
public static UnsignedLong valueOf(String string)
Returns an UnsignedLong
holding the value of the specified String
, parsed as an unsigned long
value.
NumberFormatException
- if the string does not contain a parsable unsigned long
valuepublic static UnsignedLong valueOf(String string, int radix)
Returns an UnsignedLong
holding the value of the specified String
, parsed as an unsigned long
value in the specified radix.
NumberFormatException
- if the string does not contain a parsable unsigned long
value, or radix
is not between Character.MIN_RADIX
and Character.MAX_RADIX
@CheckReturnValue public UnsignedLong plus(UnsignedLong val)
Returns the result of adding this and val
. If the result would have more than 64 bits, returns the low 64 bits of the result.
@CheckReturnValue public UnsignedLong minus(UnsignedLong val)
Returns the result of subtracting this and val
. If the result would have more than 64 bits, returns the low 64 bits of the result.
@CheckReturnValue public UnsignedLong times(UnsignedLong val)
Returns the result of multiplying this and val
. If the result would have more than 64 bits, returns the low 64 bits of the result.
@CheckReturnValue public UnsignedLong dividedBy(UnsignedLong val)
Returns the result of dividing this by val
.
@CheckReturnValue public UnsignedLong mod(UnsignedLong val)
Returns this modulo val
.
public int intValue()
Returns the value of this UnsignedLong
as an int
.
public long longValue()
Returns the value of this UnsignedLong
as a long
. This is an inverse operation to fromLongBits(long)
.
Note that if this UnsignedLong
holds a value >= 2^63
, the returned value will be equal to this - 2^64
.
public float floatValue()
Returns the value of this UnsignedLong
as a float
, analogous to a widening primitive conversion from long
to float
, and correctly rounded.
floatValue
in class Number
public double doubleValue()
Returns the value of this UnsignedLong
as a double
, analogous to a widening primitive conversion from long
to double
, and correctly rounded.
doubleValue
in class Number
public BigInteger bigIntegerValue()
Returns the value of this UnsignedLong
as a BigInteger
.
public int compareTo(UnsignedLong o)
compareTo
in interface Comparable<UnsignedLong>
public String toString()
Returns a string representation of the UnsignedLong
value, in base 10.
public String toString(int radix)
Returns a string representation of the UnsignedLong
value, in base radix
. If radix < Character.MIN_RADIX
or radix > Character.MAX_RADIX
, the radix 10
is used.
